本文介绍了一个使用Unity实现的工具提示UI组件，该组件利用MonoBehaviour类进行创建，并通过Text组件显示信息。代码展示了如何控制提示框的显示、隐藏及平滑过渡效果。

using UnityEngine;
using System.Collections;
using UnityEngine.UI;
public class ToolTip : MonoBehaviour {
    private Text offText;
    private Text mainText;
    private CanvasGroup canvasGroup;
    private float targetAlpha =0;
    public  float smoothing = 1;
	void Start () {
        offText = GetComponent<Text>();
        mainText = transform.Find("mainText").GetComponent<Text>();
        canvasGroup = GetComponent<CanvasGroup>();
	}

    void Update()
    {
        if (canvasGroup.alpha != targetAlpha)
        {
            canvasGroup.alpha = Mathf.Lerp(canvasGroup.alpha, targetAlpha, smoothing * Time.deltaTime);
            if (Mathf.Abs(canvasGroup.alpha - targetAlpha) < 0.01f)
            {
                canvasGroup.alpha = targetAlpha;
            }
        }
    }
    public void ShowTooltip(string text)
    {
       
        offText.text = text;
        mainText.text = text;
        targetAlpha = 1;
    }

    public void HideTooltip()
    {
        targetAlpha = 0;
    }
    public void SetLocalPosition(Vector3 pos)
    {
        transform.localPosition = pos;
    }
}
